I currently have my blog page set to a custom child theme, but when I go to an individual blog post, it uses the default template from my index.php. What I want is to have the individual post page have its own styling, basically a child theme specifically for the individual posts, but not for the Blog index. Does anyone know how I can do this?
In other words my default page has a container that is too wide, so I want another template with a container size that is more suitable for reading the full article.
